She said she undergoes therapy twice a month, as well as hypnotherapy to treat anxiety, and that she hopes to “inspire other women”.

Karen, who married Kevin in 2015, said they “weren’t perfect” but were a normal couple who faced “rocky moments and we didn’t know how to handle it”.

She said that the BBC One programme was the “glue” that kept them together, but that the demanding hours working on the show left them with no time to communicate, leading to the demise of their romance.

Karen is this year paired with Casualty star Charles Venn for the series, while Kevin is partnered with broadcaster Stacey Dooley.
